Not sure if anyone is still trying to keep their old AC's alive but I thought I'd throw it our there. I've replaced my mid and front roof AC units (circa 1989). I have one controller I am keeping. The other is available. Both units had their problems. One had no power to the controller. Controller was good, so I suspect the board was bad. The other unit has not operated since I got the coach. I never did any troubleshooting on it since I really did not need two AC's in the front area. Small parts I can mail. Larger items I can bring to Quartzite in January. If no takers I'll be hauling it all to the dump.

I also have two units that I can bring to WOG.
One works but needs a freeze sensor.
The second has an unidentified problem on the control board. I guess it could be the donor of the freeze sensor to the first one. I have the shrouds, interior trim, and thermostats.
